Cut a 12-inch long piece of waxed paper and set aside.

Place crushed matzo sheets in a bowl. Sprinkle with red wine and water; mix well.

Melt chocolate chips and sugar in a pot over low heat, stirring occasionally, about 5 minutes. Thin with a spoonful of water if it becomes too thick. Remove from heat.

Beat butter in a separate bowl with an electric mixer until fluffy. Gradually beat chocolate mixture into butter until well blended.

Stir matzo mixture into chocolate-butter mixture with a wooden spoon.

Pour mixture lengthwise on prepared waxed paper.

Fold waxed paper around mixture to shape into a log. Fold paper at ends to enclose the roll.

Freeze the roll until solid, at least 2 hours. Cut into slices.
